Lionel Mohawk 6-18009 Issue

A&G: This is a Pullmor powered locomotive, so standard Pullmor troubleshooting should get it running again. It doesn't sound like the motor is being supplied with electricity or it would hum/run. Could be as simple as a stuck motor brush(s). You might pop the shell off and see if the lead that goes to the plug is actually attached to something internally or not....

At the very least, I'd pop the shell and re-lube the gearbox + oil all the friction points first and then T/S your electrical issue. Also check the e-unit and see if the drum is turning during power interruptions.

I just worked on a pulmore engine where the motor was completely stalled. All it needed was a couple drops of oil down the stack on the motor. You have to take the shell off.

Thanks, Guys.  I'll try your suggestions and report back ' probably on Thursday.

I have one as just as a side note it go's around my 19 1/2" radius or 39" dia. at the center rail Gargraves curves just fine, you can hear the flanges but it doesn't slow up or anything. I believe this is the absolute min. radius.

These good looking big engines can be a real bargain on eBay today compared to what they cost when new.

I followed your suggestions but my engine still won't run.  I'm not very familiar with the inner workings of even a conventional engine like this one. 

I'm not sure what Chuck meant by a" couple of drops of oil down the stack on the motor".  And, I don't know what D&H 65 means by check the e-unit and see if the drum is turning during power interruptions.  I know an e-unit is the reversing unit, but I don't know what one looks like and what the drum is.  It may mean something when the back-up light on the tender didn't come on when I hit the direction button several times.

I belong to a breakfast group of model train operators and one of the guys was formerly a Lionel repair station.  I should call him and ask for help, before I do any serious damage.

Thanks again, everyone.

The mechanical E-unit is pretty easy to tell if it's working. In neutral, if you don't hear a consistent buzz (in the locomotive), then the E-unit may not be as responsive.

As for the oil points of the motor, here's a diagram of where those points are. In the case of the Mohawk (along with many other engines of the day), you had to remove the ashpan to get to both points of the armature shaft.

Above is a link to a  is a pictorial of your engine. The motor is mounted horizontally and you should be able to rotate the rotor in it and see if it's stuck. The ends of the rotor are mounted in bearings and they need to have a drop of oil on each end. It one I just serviced was mounted vertical and had a short plastic top with a hole in the midde on it's top where you could drop oil into it. 

Your engine has a mechanical e-unit which has a little drum at the bottom of it. You can see if it turns when you cycle the voltage on and off. It's number 54 in the diagram.

You guys are the best.  I really appreciate the diagrams.  I'm going to put it away until after Christmas, then try again.

Thanks again, everyone. And Happy Holidays.
